' The invention relates to .improvementsin oil burners, moreparticularly tc that'type of burner which vis to be used n COIlJllIlC-tion with a fire pot of a furnace, and the the said ThomasC; EspositoOctober 21,

1924, one specific object of the present i111? provement beingtogdispense with the generator described said. Letters Patent and to'provideian improved form of generator which is arranged within 'thecombust on chamber, which increases the efiiciency of the burner andenableseconomies to be efiected in the construction thereof;

Another Object is" to provide means for equally distributing the fuelover the surface of the generator. 7

A futher object is to pr I event clo gging of the fuel supply pipe.

Still another object is to' properlyand uniformly heat the lowercircumferentialportion of-the generato'r'when f starting the burner andprior to supplying the fuel,

ignition of which ,takes place along the lower circumference of thegenerator;

the invention consists in the construction, combination and arrangementof -devices hereinafter described and claimed. j

, In the accompanying drawings Figure 1 is a vertical central sectionalin accordance with this invention. 7 s

, Figure 2 is a; horizontalseetional view of the sameon the planesindicated by the'line 2+2-of'Figure 7 i The burner ncludes'a base member10 which consists of a circu1ar mun and a cover portion l2 which ispreferably integral therewith and which has a central'sub- -stantiallyfrusto conical portion 13 which isprovioled at its upper part withopeningsf '14 and also with a central threaded opening 15 The saidcover712 forms a chamber 16 in its upperside and is provided with anupstanding concentric flange' 17 and also with a suitable number, ofappropriately spaced tubular members 18 which are open at the upperandlower ends.

An annular member 19, which is open rality of tubular members 24. Eachmember has at the lower edge of its wall a at the lower side and whichis closed at'thelupper side asat 20 is provided with a 'plushoulder 21which fits on a corresponding shoulder 22 with which the upper edge ofthe wall of each tubular member 18 is pro v.

vided. Said annular" member also hasan inverted ffrusto-conical wall 23which 'depends from its top20. and which is'above and concentric withthefrusto-conical extension 13 of the base 10'. Said tubular members 18andi24 open into the chamber 25 which is formed within the invertedfrusto-conical 'wallf23, through openings 26, aswwill be understood. Thediameter of the lower end of the zwall 23 is considerably greater thanthat ofthe upper end ofthe frusto -conical extension 13 so that anannular onen' space 27 is formed therebetween, as

shown; 7 i

' The top 20 of the V providedjwith a central opening 28 and alsoannular member 19 is with acircularfupstanding flange 29 which extendsaround and is spacedfrom said openin'gffA cover 30;i's provided which31, said cover having a central opening to receive said plug and saidplug having an A1 fuel supply pipe 33 extends upwardly bears on the topoffthe member 19 and withi in theiflange 29 a'nd is provided with'a plugc 1 With the above and other objects in view,

through and isthreadedly engaged in the opening 15 of the-base, theupper end of said fuel supply pipe projecting above the frusto-. conicalextension 13 of the cover of the-base. I

There is also animproved generator which serves to crackthe fuelfoil andto convert the same into vapor to unite with air within ,the chamber 25and thusform a highly infiammablegas; Said generator is indicated at 34=and is of 'frusto-conical form provided with-a correspondingly shapedrecess 35 inits underside and provided in its'upper end with',a cup 36.The upper end ofithe fuel supply pipe 33 extends through and is threadedto said generator, the extreme upper end of said pipe being arranged andextending up through the. center of; the cup 36. l i

The said member 34 is provided on its exterior with downwardly extendinggrooves which at the lower end. ofusaid member terminate in open spacesbetween whichlie tooth like downwardly extending projections 38. Insideof said tooth like projec tions and opposite each second space isanother depending tooth like projection 39. These, g o es. andpr jcc ins s ve to enly distributethe fuel oil which flows downwardly from thepipe 33 and' cup 36 over the exterior of the member 34 as will beunderstood;

Anoverfiow pipe 4 0 leads from the basin or chamber 16, of the basemember 10. A gaspipe 4 1, for use in starting the burner is arrangedwith its upper end below the top of the frusto-conical extension 13 ofthe base as shown.

The operation of this improved burneris as follows: In Order to startthe burner in operation, gas from the pipe 41 is ignited, the flam pa ss hr gh t e'space fo med bet-ween said member 34 and said frustoconicalextension 13, and through the spaces fo 'met l between :the projections38, espeia y, hro g v ry the spac as he pat throughalt'crnate spaces. isblocked bythc inner projections 39. hen the member'34 is. sufficientlyheated, the fuel oil is then caused to be supplied by the pipe 33 to thesaid" generator member 34;, such oil first filling'the cup 36' andoverflowingtherefrom on to and passing down over the exterior surfaceof, said niemberfid. Owing to the ea e c ndit o o such nmmbc th l a itpasses downwardly over the same is cracked and converted into vapor,being distributedfand its cracking and vaporizing facilitated by thegrooves 37 and projections 38, 39 before described. Air enters thechamber 25 of the burner, within the member 19, through the ducts ortubes 18, Qtand becomes commingled with the vapor, thereby forming ahighly inflammable gas which passes downward through the annular spacebetween the lower edge of the wall 23 and the member 34: and ignitesnear the highly heated lower circumference of the generator, the flamespassing radially out- \vardly therefrom, as shown in the drawings. Theair intake is represented by the arrows a andYthe direction of thepassage of the vapor and of the flame is indicated 1 by the arrows ZNojmeans is employed for regulating the supply of air to the burner asthis is effected automatically.

The cover member described in the before .mentioned Letters Patent maybe employed or may be dispensed with as desired. The burner s here shownas without such cover.

- By removing the member 30 access may be had to the interior of theburner to facilitate assembling and dissembling thereof. In practice theburner requires very little attention and rarely requires to be cleaned,as the residues from the oil are nearly entirely consumed, and aspractically no carbon is form d" wh n start ng th d v e. owin to thefact that the fuel is uniformly distributed over the surface of thegenerator and that the generator is uniformly preheated and has a highlyheated lower circumferential portion along which ignition takes place.The Zone of ignition is therefore also far removed from the pointofsupply and the supply overflow pipe'is of liberal dimensions,so thatclogging of the supply pipe by carbon is eliminated. This was one of theobjectionable features of the older construction, which furthermorenecessitated frequent cleaning of the supply pipe in view ofaccumulation of heavy volatile'fractions of the fuel oil. Inthe eventthat any of the oilescapes combustion in the burner, the same will pass.out from the base member through the pipe 40. lV'hen it becomesnecessary to clean the upper end of the fuel supply pipe 33, the plug3.1 may be readily removed to enable asuitable instrument to be readilyinserted into the upper end of id pipe 1 i While there is herein shownand described a preferred embodiment of the invention, it should beunderstood that changes may be made in the form, proportionand'construction ofthe several parts, within the scope f th app nde cla m 1Having'thus described the invention, what i cl im dis 1 1..
